Question

It is possible to shoot an arrow at a speed as high as 105 m/s.(a) If friction is neglected, how high would an arrow launched at this speed rise if shot straight up?

Answer 1

I would use an equation of motion for this.

u=105m/s

v=0

s=?

a= -9.8 m/s^2

so use   v^2=u^2 + 2as

      0= 11025 + 2(-9.8)s

19.6s= 11025

      s=  562.5m

Then you may have to put it to 3 s.f giving 563m

Hope that helps!!
